var notification = new NotificationRequest

        NotifyTime = DateTime.Now.AddSeconds(30) // Used for Scheduling local notification, if not specified notification will show immediately.
    }
};

			.WithScheduleOptions((schedule) => schedule
					.NotifyAt(DateTime.Now.AddSeconds(30)) // Used for Scheduling local notification, if not specified notification will show immediately.
					.Build())
                        .WithTitle("Test Title")
                        .WithDescription("Test Description")
                        .WithReturningData("Dummy Data") // Returning data when tapped on notification.
                        .WithNotificationId(100)
                        .Create());

With platform specific options

await NotificationCenter.Current.Show((notification) => notification
                    .WithScheduleOptions((schedule) => schedule

					.Build())
                    .WithAndroidOptions((android) => android
                         .WithAutoCancel(true)

                         .WithPriority(NotificationPriority.High)
                         .WithOngoingStatus(true)
                         .Build())
                    .WithiOSOptions((ios) => ios
                        .WithForegroundAlertStatus(true)
                        .WithForegroundSoundStatus(true)
                        .Build())
